About Us

Magnum Superchargers was established in the late 1970's, by its current
owner, Gary Hedden. Gary had been involved in drag racing in the Upper
Midwest and Canada for years, having spent time working in various
speed shops, such as L & L in Thunder Bay, Ontario, and J & J in
Crystal, Minnesota. Over its lifetime, the shop has been involved in the
construction of many drag and show cars, such as the famous and
ground-breaking '55 Chevy Pro Streeter of Gary Kollofski.

While we have always offered custom engine-building, from street-rod to
full race, as well as custom blower and fabrication-building services, our special
focus has been on developing high-horsepower, streetable, pump-gas engines.

Often, when a customer visits the shop, with the preconceived notion that he
is looking for a race-gas engine, he will find that he receives first a bit of
education on... (continued)

...the real facts: that while it is indeed sometimes completely necessary to
take advantage of the high-compression capabilities of race gas, it is also many
times utterly unnecessary to do so. It is not enough just to say so though, which
is why most Magnum Superchargers engines undergo dyno testing before delivery.

This type of advice has always flown freely at Magnum Superchargers. When
your application really does require something more exotic, we will be happy
to provide it, but first we will make sure that is really what you need.
